@peemee Oh, interesting! "Cordial" to me is another word for liqueur, but this is a squash, instead. I've mostly run into it in the context of a cordial glass. Hadn't heard cordial used to describe a squash before before.
Terminology aside, it sounds tasty! I enjoyed squashes while I was in Hong Kong, and I've picked up some from the British section of the grocery store now and again.
